A Russian former police officer, who is serving a prison sentence in Russia for having spied for the United States Central Intelligence Agency, has written an open letter to President Donald Trump, asking to be freed. Yevgeny A. Chistov was arrested by the Russian Federal Security Service (FSB) in 2014 on charges of spying for Washington. During his trial, he admitted having been recruited by the CIA when he worked as an officer in the police, Russia’s federal law-enforcement agency, which operates under the Ministry of Internal Affairs. Russian state prosecutors accused him of having established contact with the CIA in 2011. In 2015, he was sentenced to 13 years in prison, which he is currently serving at a labor camp in the Nizhny Novgorod town of Bor, located in central European Russia.

On Saturday, British newspaper The Guardian published a letter that was allegedly written by Chistov. In the letter, the jailed spy admits that he passed Russian state secrets to the CIA for three years, after deciding “to help the US as a friend”. He claims that he did it out of love for his country, and in order to help “overthrow […] the regime” of Russian President Vladimir Putin. Chistov goes on to accuse “Putin and his cronies” of having plundered Russia and of oppressing its people through “corruption and extortion”. He blames the Kremlin for Russia’s current economic state: “we have a resource-rich country yet our people are poor”, he says. The jailed spy adds that he told the CIA about the “secret plans” of the Ministry of Internal Affairs, that he provided “names of some people from the FSB”, and that he “revealed some objectives of Russia’s Ministry of Defense”. He does not provide details. He then claims that, even though he was paid by the CIA for his services, he did not act out of self-interest.

Chistov says that the conditions of his imprisonment are inhumane and that he and his family “are in great danger in Russia”. He also claims that his wife visited the US embassy in Ukraine in an attempt to secure a travel visa, but that her application was rejected and she was forced to return to Russia. The jailed spy adds that he “wrote two letters to the CIA asking them to help and received no response”. He then pleads with President Trump to help him, in two ways. First, by granting asylum in the US to his wife and mother. Second, by swapping him with someone “who worked for Russia” and is serving time in a US prison. “I want to appeal to the president to conduct the exchange”, he concludes.

The United States has participated in very few spy swaps in the post-Cold War era. In 2010, Washington and Moscow conducted one of history’s largest spy exchanges, as ten deep-cover Russian agents captured in the US earlier that year were swapped for four Russian citizens imprisoned by Moscow for spying for the US and Britain. Four years later, a Cuban intelligence officer who spied for the CIA was released as part of a wider exchange between Washington and Havana of persons held in each other’s prisons on espionage charges. The White House has not commented on Chistov’s letter.
